CO2 Tank System

By Jeep Experts

If you might be in any respect into wheelin’, you most likely know that lowered tire stress gives you with higher traction, amongst different issues.  Running low tire pressures additionally permits the tire to adapt to these sharp rocks and thus reduces the probabilities of you shredding a tire.  But….as soon as you might be on the finish of the path, it’s essential to fill these tires again as much as their regular avenue stress earlier than heading for dwelling.  Running lowered tire stress on the road is NOT one thing you wish to do.  An everyday air tank, stuffed from the storage air compressor, doesn’t maintain sufficient air to fill these meaty off-road tires.  If you don’t want to set up a belt pushed York compressor below the hood and a 12V compressor will not be in your record of precedence mods, then you definitely would possibly wish to contemplate a CO2 tank.

Powertank provides a wide range of prepared constructed CO2 programs.  They are quite costly, in my view.  However, I’ve by no means heard anybody complain concerning the high quality of the gear so it seems you might be getting what you pay for.  The Powertank additionally comes with a few issues I don’t contemplate essential, such because the gauges.  CO2 tanks keep a comparatively fixed tank stress till simply seconds earlier than they’re empty.  As such, a excessive stress gauge related to the tank is of little use.  It will point out the tank has good stress till it’s simply 15 seconds from empty.  Wow, that’s actually helpful info if you find yourself out on the path.  Unless you propose on operating an adjustable regulator (extra about later), having a gauge to watch the output stress can also be of no use.  The Powertank website has some good studying information on it and I recommend anybody desirous about a CO2 system to spend a while and browse the positioning.

You could make your individual CO2 system, skip the center man, and pocket the cash you save.  You don’t want any particular instruments for this undertaking (now that’s good for a change!) and upon getting bought the elements, it ought to solely take you a couple of minutes to assemble it right into a working CO2 system.  I’ve heard that tanks will be had on eBay and such locations for a really cheap worth.  As with so many Jeep associated initiatives, take you time, do your homework, and you must have the ability to avoid wasting cash and find yourself with a job properly executed.

Here is my CO2 system.  It consists of a ten# aluminum tank, mounted stress regulator, and supply hose.  The the rest of this write-up will go into slightly extra element concerning the system and security options.  Let’s check out what I’ve used on my CO2 system.  This write-up will not be trying to let you know what’s finest or what parts you could buy.  Instead, I hope to give you sufficient info that it is possible for you to to place collectively a CO2 system that may fit your wants and never trigger you to spend greater than is important.


Here is the hose, stress regulator, tire chuck, and blow nozzle that I exploit on my CO2 tank.  The air chuck, blow nozzle, and fast disconnects that connect them to the hose have been obtained from the native ACE Hardware retailer.  Nothing fancy there…..these are the identical ones you’ll use on any common air tank.  While the first use of this CO2 system is for filling my TJ’s tires, I’ve to confess that the blow nozzle is fairly useful for getting these mud bunnies out of the within of the PC! 

I purchased my CO2 system from a buddy of mine who had received it in a raffle.  It had been assembled by a CA firm who makes a speciality of a wide range of gasoline merchandise.  As such, my tank was put along with, what I imagine to be, higher high quality parts than the typical ironmongery store selection undertaking.  Here is the becoming that attaches the hose to the regulator.  It is a screw on becoming that solely must be finger tight with a purpose to haven’t any leaks.  The becoming has particular grooves reduce by means of the threads that safely bleeds the stress once you unscrew it (after use). 

The regulator is a hard and fast stress unit that gives roughly 150 PSI output.  I don’t know the movement charge (they make excessive and low movement regulators) of this regulator but it surely does a great job on filling tires.  If you require a particular output stress kind the regulator, similar to 90 PSI for an ARB air locker, it would be best to spend just a few extra {dollars} and buy an adjustable regulator with an output stress gauge.  A superb buddy of mine makes use of his CO2 system to energy his ARBs and it really works nice.  He has a small (low movement) regulator that price him about $25.  It is on the tip of a fast disconnect becoming so he an simply join it to the CO2 tank when he hits the path and makes use of his lockers.  At the tip of the path, he pops the hose (going to the adjustable regulator) off the tank and makes use of it to fill his tires.  The small adjustable regulator is fed from the 150 PSI mounted regulator.  Doing it this fashion permits him to depart the mounted regulator related to the CO2 tank on a regular basis.

The hose I exploit is particularly made for CO2 and nitrogen tank programs.  As will be seen within the photograph above, the working stress of the hose is 600 PSI and the burst stress is 2200 PSI.  These rankings are most likely over kill contemplating the hose sees simply 150 PSI when the CO2 system is in use.  However, if my regulator have been to fail open (I don’t know if the design would permit that to occur), the hose ought to survive the regulator failure.  Normal tank stress is within the 700 PSI vary.

I received my buddy to snap an image of his CO2 tank.  His doesn’t have the deal with/valve protector on it like mine does.  This is a typical metal tank that’s exchanged for a full tank on the native weld store.  The regulator is a hard and fast stress regulator (model unknown).

CO2 Tank System

Speaking of regular tank pressures, I’ll go alongside the small print of a scenario I skilled simply final summer season.  It concerned a visit to the native welding provide retailer that I had been frequenting for a lot of CO2 refills.  The weld store was solely about 3 miles from my home and in contrast to many retailers, they’d fill your tank when you waited.  Many of the opposite retailers would solely alternate your tank for a stuffed tank.  When you have got a pleasant aluminum tank with a cool carry deal with on it, the final suppose you wish to do is alternate it for beat to crap metal tank.  Because of this, I continued to make use of this store for my refills.

It was mid summer season, which suggests it was over 110 levels, right here in Phoenix.  I finished by the weld store they usually stuffed my 10# tank.  I drove dwelling and set the tank on the work bench within the storage.  About 3 or 4 hours later, I heard this roaring noise that sounded similar to a freight practice.  It took me a few seconds earlier than I spotted what it needed to be… freshly stuffed CO2 tank had reduce unfastened and was venting extra stress.

Now it’s a must to notice that the surplus CO2 gasoline doesn’t merely vent till it’s again to a protected stress….as a substitute, it begins venting and continues till the tank is totally empty (and to not point out chilly sufficient to freeze the brass nuts off a metal bridge!). 

Here is an image of the protection aid that every one CO2 tanks have.  Yours could look slightly totally different, however it should serve the identical function….if the stress will get too excessive, it should blow out and launch stress.

If it ever ought to blow, you’ll have to change it.  They unscrew from the valve meeting and the enterprise finish of it appears to be like like this.  The gap is the results of the stress build up and finally rupturing the skinny steel burst disc.  My aid was rated at 3000 PSI…..WOW….that could be a bunch of stress when you think about that the traditional working degree is round 700 PSI.  What triggered the stress to spike so excessive?


A ten# CO2 tank will maintain 10# of CO2 when it’s correctly stuffed.  I stress the phrase correctly as a result of an overfilled CO2 tank, when subjected to summer season temperatures, will rapidly construct up sufficient stress to blow out the 3000 PSI burst disc.  When my burst disc blew, I contacted the corporate who had constructed my tank (for a alternative) and spoke with certainly one of their prime workers.  By then, I had heard all manners of horror tales about CO2 tanks blowing up within the Phoenix summers, and many others.  He assured me {that a} correctly (there’s that phrase once more) stuffed CO2 tank will be half buried within the Mojave desert, all summer season lengthy, with none likelihood of it venting.  It will not be till the tank is overfilled AND ambient temperature is excessive that the recipe for a blowout is cooked up.  I discovered some associated CO2 tank filling information on the Internet however I’ll admit it was too technical for me to totally grasp.  It went into element as to how the stress spikes, based mostly on the p.c of overfill and the temperature (amongst different issues mentioned).  I used to be capable of glean sufficient from it that I felt snug with what the gasoline tech man advised me on the cellphone.

By now, you ought to be asking your self how YOU are going to keep away from getting your self into this sort of scenario.  After all, you might be placing vital religion into the skills of somebody that you just most likely don’t know and hopefully can depend to 10 when he fills your CO2 tank.  One factor that I used to be NOT doing earlier than my tank venting state of affairs however now do after refill is to easily weigh the tank.  The above reveals the tare (empty) weight of my aluminum tank, which is 14.5 lbs.  That signifies that the tank ought to weigh 24.5 lbs. after it’s stuffed.  If it weighs greater than that, I might hook up the regulator and hose and bleed some CO2 off earlier than the burst disc determined to do its factor.  Just weigh your tank earlier than you’re taking it to the shop for a refill and instantly weigh it once you get dwelling.  I might recommend that you just don’t do that very first thing within the morning after which not plan on weighing it till later within the afternoon.  On a heat day, that might be greater than sufficient time for the stress to construct on an overfilled tank.  Please perceive that I’m NOT trying to scare the dickens out of you and maintain you from utilizing a CO2 tank.  Actually, it’s fairly the opposite.  I would like you to be totally conscious of a CO2 tank’s operation so you’ll be able to correctly use it with out worry of it having an issue.

CO2 is an excellent transportable air supply.  My used CO2 system ran me $100 (tank, regulator, and hose).  I’ve used it on the path, within the storage, in the home, and on the car parking zone.  If you determine to go together with a CO2 tank, I hope you get pleasure from yours as a lot as I’ve mine.

P.S.  In case somebody was questioning, I finished utilizing that welding provide store.  I went again the next day and requested a refund of my cash.  I used to be politely knowledgeable that it was my fault the tank over-pressured…..the fool behind the counter claimed I mustn’t have saved it in my storage.  I requested him about the entire CO2 bottles at his retailer that sat outdoors in a non air-conditioned storage shed….DUH…..he couldn’t consider a great come again for that one!   I now have my tank stuffed at a industrial fireplace extinguisher store….they’ve but to be an issue….and one of many worker that works there thinks my TJ is fairly good.  How can I am going unsuitable?

CO2 Tank System

OK… you bought your CO2 tank assembled and also you’ve checked it out.  It is working superior, proper?  Super!  Now…..what are you going to do about that plain wanting tank?  What, you haven’t on condition that any thought?  Oh oh….unsuitable reply.  You gotta costume it up slightly bit.  Besides, all of us customise our Jeeps….you definitely don’t need your CO2 tank wanting just like the CO2 tank in your buddy’s TJ, proper?   Here is what mine now appears to be like like.

Through the wonders of the web, I connected with a Jeeper named Todd who additionally occurs to be fascinated by scuba diving.  (I’m licensed however its been about 15 years since I final was within the ocean with a tank on my again.)  Anyway, Todd can also be a graphic artist and he designs and sells his “Scuba Hides” to the scuba diving crowd. 

Scuba Hides are a non-adhesive 2-ply tank cowl.  The graphic is printed on a ten mil thick sheet of polyethelyne which is positioned across the tank with none adhesive.  A clear 5 mil thick shrink-wrap sleeve is then slipped over the tank/graphic.  This outer sleeve is shrunk-to-fit with a daily hair dryer.  Because the graphic is below the protecting sleeve, the graphic doesn’t rub off.  The entire setup is water and UV proof so having it strapped within the rack behind your TJ with the highest down shouldn’t damage it.

Since Todd’s graphics are at the moment made for the everyday scuba tank, they’re slightly tall when put onto a ten# CO2 tank.  However, for these of you operating a 15 or 20 pound tank, you might not must trim something.

My spouse, Donna, loves to stitch.  Quilting is certainly one of her favourite hobbies (much more in style than working the video digital camera for me on the path runs) and so I requested her abilities once I began placing the graphics on the tank.  While I may have discovered a scissors or field knife and reduce the graphic to suit my 10# tank, Donna agreed to make the reduce for me.  She follows the previous “measure twice, reduce as soon as” technique whereas my outcomes are extra like “I reduce it twice and it’s nonetheless too quick!”.  Needless to say, she made very quick work of the duty and I had a 12″ tall graphic very quickly in any respect.

The grahpic is designed to depart a niche on the cylinder.  On scuba tanks, you cannot cowl the visible inspection sticker, so the graphic is sized to depart a niche the place the sticker will be displayed.  Since the hole was there, I positioned the graphic in order that my CO2 sticker could possibly be views (or not less than most of it anyway). 

With graphic on the tank, slip the protecting sleeve over the tank.  I had Donna reduce this for me in addition to it too was longer than desired.  She trimmed it to 13.5″.  The instructions that got here with the Scuba Hide mentions that the sleeve wants to increase previous the graphic by about .5″ on each ends.  I opted to make mine slightly longer because it was my intention to have it comfortable across the tank’s tapered shoulder only a bit. 

CO2 Tank System

A fast journey to the lavatory resulted in a single hair dryer, the remaining “software” I wanted to finish this undertaking.  I have to admit that that is the primary time I’ve executed one thing in relation to my TJ the place my spouse’s stitching room and the lavatory yielded the mandatory instruments wanted for the undertaking. 

Take it straightforward with the hair dryer.  Keep it shifting and don’t focus an excessive amount of warmth in a single spot for too lengthy.  I discovered that working my manner across the tank and shrinking the fabric slightly at a time after which shifting on appeared to work the very best.  Todd consists of two sleeves with every graphic and the reality be identified, my first try was inferior to I wished it to be.  So, I peeled it off with a razor knife and used the second sleeve.  Attempt quantity two was a lot better.

So there it’s with the sleeve shrunk across the tank.  On mine, the sleeve really catches the sting of the tank, each on the higher and decrease fringe of the graphic.  So it’s on there very properly to say the least.  I don’t see it sliding round or coming unfastened. 

You can view all of Todd’s useful work at  You can order one one-line for simply $20 or name 800-375-4628 ext. 88.  If your 4×4 membership or enterprise is fascinated by a customized design, Todd could make these too in portions as small as 10 for simply $25 every.  Get in contact with him for particulars on the type of graphic he wants from you, and many others.  I believe it could look fairly sharp if a membership had all of their tanks coated with their emblem.  What I’m personally hoping for is that Todd sees a great quantity of curiosity from the 4×4 people and begins making some common choices which might be focused in the direction of our pastime. 

So the subsequent time you might be on the air-up spot, I hope your CO2 tanks appears to be like pretty much as good as mine.  If it doesn’t, you bought all the data it’s essential to right the issue.   An enormous due to Todd too for answering all of my questions.
